Review on DZS Elec Optocoupler Isolation Triggered by Aaron Urena
Works great with ESP32
I'm using it with an ESP32 development board and so far so good, reliable. Very good is that it has jumpers to toggle between HIGH and LOW.
- patch element opto-isolator, green power indicator, red relay status indicator, strong driving ability, stable performance, clear working condition.
- Questionable purchase for the elderly
